SPECIFICATION forming part of Letters Patent No. I217,282, dated December 30, 1902A.

Application filed December 28,1901. l Serial No.V 87,537- (No model.) l

To all whom it nung-concern.-

Beit known that I, WILLIAM D. RUNDLETT, a citizen of the United States,residingat North Andover', in the county of Essex and State of Massachusetts, have invented an Improvement in Adjustable Eccentrics, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing Io like parts.

In condensers wherein aprons extended over rollers lare made not only to travel to' feed the slivers, but are also reciprocated to condense the slivers,.the rollers carrying the aprons are reci procated by eccentrics-as, for

instance, in UnitedStates'PatentNo. 266,414, dated October 24, 18,82.

The invention herein to be described has relation to reducing the wear on the eccen` 2o trios, and to do this I have devised a new ec`` centric and have made novel provision for tached. Fig. 3 is a section in the line oc, Fig.` 2, of the parts shown in said ligure with part 3o of a carriage; and Fig. 4 is a section in the! line Referring to the drawings, A represents stationary uprights at the delivery end ofthe carding-machine; la, horizontal guideways ex- 3 5 tended therefrom that .receive and guide the slide or carriage a', to which are fastened boxes for sustaining the usual rollers that are surrounded by the condensing-aprons common to said patent. V

B represents a vertical shaft which may be rotated in any usual mannerl common in condensers used with cardingimachines.

In this class of machine when the vertical shaft'B and its usual cccentrics are rotated at a high speed the lubricant is quickly drained from the Wearing-surfaces, and unless said surfaces are oiled frequently thel eccentrics are liable to be overheated and destroyed, which results in the stopping' of the machine 5o until new eccentrics are substituted. Ihave aimed to construct the parts in such manner that the oil applied to the eccentrics must traverse the entire wearingsurfaces and finally enter and be retained in a suitable receptacle of such shape or character that the `oil may be again returned to the wearing parts whenever the'machine is stopped, at which time the parts are liberally fiooded with oil. yI have aimed to reduce the rapid wearing of `th'e apron-feeding shafts and to reduce the ,wearon the parts to be described.

The slide or carriage a' (partially shown in IFigs. 2 and 3) has a drilled socket a2, which is entered by a preferably hollow stud c, exltended froxnan eccentric-strap C, the stud `being hollow to receive and retain a quantity `of oil to-thoroughly lubricate the connection fbetween the strap and slide. The strap near its other end has an annular flange c' of a width to enter` an annular groove in an eccentric or block D, surrounding loosely the shaft B and free to be adjusted laterally into any position of eccentricity with relation to said shaft; The inner side of the outer wall ofthe annulargroove in the eccentric or block D has a series of segmental pockets d, and preferably the exterior of said annular flange c' has an oil-groove and annularprojection c2 substantially opposite the series of pockets d, `said groove and projection causing the surplus oil t`o be discharged into the annular pockets and thereretained until the eccen tric is stopped, at which time the oil returns `bygravity to the wearing-surface and again lubricates the same. These pockets are com- `posed of agroove interrupted by partitions dx, (shown by dotted lines, Fig. 2,) said partitions checking the circnlar'ow of the oil with the flange c. The strap has an oil-hole at c3, which isibored angularly through said ange, as `fshown in Fig. 3,so that oil applied to the oil-'hole which is located in the `nonrevolving part will be delivered on the outside oftheinner wall of said eccentric, where it is difficult to apply the oil when the eccen- 95 tric isrunning, owing to the tendency of the oil to fly outwardly, due to centrifugal action. Portions of the strap O extend over the annular groove in the eccentric or block and cover and protect the oil used in lubri- Ico vIO cating the eccentric. The eccentric or block is shown as circular externally and as having at its bottom side slots 2, shaped as shown by dotted and full lines, Fig. 2, said slot having leading from it a straight throat 3. The hub f, secured to the shaft B by suitable set-screws 4 and provided at its lower end with a plate f integraltherewith, is extended through the slot 2 in the end of the eccentric or block. The plate f has, as shown, two slots 5, (see dotted lines, Fig. 2,) through Which are passed two screws 6, provided with suitable Washers 7, theinner ends of the screws entering threaded holes in the bottom of the eccentric or block at the sides of the slot 2. By loosening the screws 6 the eccentric or block may be moved laterally with relation to the longitudinal center of the shafts B to provide for altering the throw of the eccentric and the slide or carriage, according to the requirements of the machine, a stud 8, rising from the plate f', sliding at such time in the throat 3 of the eccentric or block. The stud 8 acts as a pointer and cooperates with graduations l0 at the upper sides of the throat 3 to indicate the extent of adjustment of the eccentric or block.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A hub, a block having au annular groove at one side, means to adjust the block on said hub with relation to the longitudinal axis of said hub, and an eccentric-strap having an annular fiange entering the said annular groove. l

2. A hub, a block having an annular groove at one side, means to adjust the block on said hub with relation to the longitudinal axis of said hub, and an eccentric-strap having an annular flange entering the said annular groove, said strap having an oilfhole leading from the outer side through said flange to the wall of the annular groove nearest the center of said hub.

3. A hub, an eccentric or block having an annular groove provided at the inner side of its outer wall with a series of pockets or spaces separated by partitions, said pockets receiv-A ing and holding oil.

4:. A hub, an eccentric or block having an annular groove, an eccentric-strap having an annular iiange to enter said groove, said strap having a groove to lead oil to the inner wall of said annular groove.

5. A hub, an eccentric or block having an annular groove provided in its outer wall with a series of spaces for oil, an eccentric-strap having an annular flange to enter said groove and provided with a'n oil-discharging groove and ring at its outer face.

6. A hub having at one end a slotted ange and provided with a stud, and an eccentric or block, screws connected with said eccentric or block and free to be moved in said slots to adjust the eccentric or block on said hub, said eccentric having a slot to be entered by said stud to operate substantially as described. e

7. A hub, an eccentric or block having an annular groove in one side or face thereof, oilpockets disposed in the wall of said annular groove, and an eccentric-strap having an annular ange extended from one side or face thereof to engage said groove in the block, said strap extending over the annular groove in the block to cover and protect the oil used in lubricating the eccentric.

-8. A hub, an eccentric or block having an annular groove in one side or face thereof, oil-pockets disposed in the wall of said annular groove between the top and bottom thereof, and an eccentric-strap having an annular flange extended from one side or face thereof to engage said groove in the block, said strap extending over the annular groove in the block to cover and'protect the oil used in lubricating the eccentric.

ln testimony whereof I have signed my name to this specication in the presence of` two subscribing Witnesses.
